The party will first face a champion flaming effigy. During the fight, the party will also be attacked by a patrol of Molten alliance coming down the slope, which can take the party unaware.

The party then reaches a large platform. Once upon the platform, a short video sequence will introduce the Molten Berserker and Molten Firestorm, bosses of the fractal. Both must be defeated to finish the fractal.

The Molten Berserker (blue charr) shadow steps around the platform and shoots out circular shockwaves. Note that one type of shockwave, caused by the stomp, can be jumped across, saving endurance. The Molten Firestorm (advanced Dredge power suit) flitters around the platform shooting flaming AoE shots at the party that persist on the ground for several seconds. Shockwaves and flaming projectiles both cause Agony.

Every time one of the bosses loses 25% health, the other one will become Enraged, significantly increasing the rate at which he uses his skills and consequently his damage output. It's possible to remove the Enraged buff by hitting that boss 50 times (every hit removes a stack), after which it will become stunned for a few seconds. Another option is to concentrate only on one boss, enduring the other one in Enraged state for nearly the whole duration of the fight.

Once one of the bosses is defeated, the surviving boss will walk to the corpse and "upgrade" his attacks. The Molten Berserker gains an improved stomp and causes debris to fall down on the platform, while the Molten Firestorm creates a storm on the platform that significantly limits the area the party can stay in. Players caught in the storm will likely be thrown off the platform, which will kill. However any players that have died will revive at full health once one of the bosses are defeated.
